CHIPSEA CS32F031K8U6H

The CS32F031 series microcontrollers feature a high-performance 32-bit ARM Cortex-M0 core, with up to 64Kbytes of flash and 8Kbytes of SRAM, operating at a maximum frequency of 48MHz. The 031 series includes 3 different package types, covering multiple products ranging from 28-pin to 48-pin configurations. The devices provide standard communication interfaces (I2C, SPI/I2S, and USART), one 12-bit ADC, seven 16-bit timers, one 32-bit timer, and one advanced-control PWM timer. The CS32F031 series microcontrollers operate over a temperature range of -40°C ~ 105°C and a supply voltage range of 2V ~ 5.5V. The devices offer a range of power operating modes to meet various low-power application requirements. The CS32F031 series microcontrollers are suited for a wide range of applications, including controllers, handheld devices, A/V receivers, PC peripherals, gaming and GPS platforms, and industrial applications.
